This book describes the development of the power matching problem. It starts with the derivative-free proof of conjugate matching, goes through the nonlinear, resistive maximum power theorem and its reversal, extension of the concept of equivalence in the case of nonlinear circuits, application of the nonlinear, and resistive maximum power theorem for diode measurement. The author treats practically important special cases of nonlinear, dynamic power matching with applications, and the most general solution that is not realizable.

Theory and Design of Broadband Matching Networks centers on the network theory and its applications to the design of broadband matching networks and amplifiers. Organized into five chapters, this book begins with a description of the foundation of network theory. Chapter 2 gives a fairly complete exposition of the scattering matrix associated with an n-port network. Chapter 3 considers the approximation problem along with a discussion of the approximating functions. Chapter 4 explains the Youla's theory of broadband matching by illustrating every phase of the theory with fully worked out examples. The extension of Youla's theory to active load impedance is taken up in Chapter 5. This book will be useful as a reference for practicing engineers who wish to learn how the modern network theory can be applied to the design of many practical circuits.
The third edition presents a unified, up-to-date and detailed account of broadband matching theory and its applications to the design of broadband matching networks and amplifiers. A special feature is the addition of results that are of direct practical value. They are design curves, tables and explicit formulas for designing networks having Butterworth, Chebyshev or elliptic, Bessel or maximally flat group-delay response. These results are extremely useful as the design procedures can be reduced to simple arithmetic. Two case studies towards the end of the book are intended to demonstrate the applications to the practical design of modern filter circuits.
RF CMOS Power Amplifiers: Theory Design and Implementation focuses on the design procedure and the testing issues of CMOS RF power amplifiers. This is the first monograph addressing RF CMOS power amplifier design for emerging wireless standards. The focus on power amplifiers for short is distance wireless personal and local area networks (PAN and LAN), however the design techniques are also applicable to emerging wide area networks (WAN) infrastructure using micro or pico cell networks. The book discusses CMOS power amplifier design principles and theory and describes the architectures and tardeoffs in designing linear and nonlinear power amplifiers. It then details design examples of RF CMOS power amplifiers for short distance wireless applications (e, g., Bluetooth, WLAN) including designs for multi-standard platforms. Design aspects of RF circuits in deep submicron CMOS are also discussed. RF CMOS Power Amplifiers: Theory Design and Implementation serves as a reference for RF IC design engineers and RD and R&D managers in industry, and for graduate students conducting research in wireless semiconductor IC design in general and with CMOS technology in particular.
First published in 1978, this book rapidly established itself as a classicof modern Marxism. Cohen's masterful application of advanced philosophicaltechniques in an uncompromising defence of historical materialism commandedwidespread admiration. In the ensuing twenty years, the book has served as aflagship of a powerful intellectual movement - analytical Marxism. In thisexpanded edition Cohen offers his own account of the history, and the furtherpromise, of analytical Marxism. He also expresses reservations abouttraditional historical materialism, in the light of which he reconstructs thetheory, and he studies the implications for historical materialism of the demiseof the Soviet Union.
Shinohara and co-authors present a comprehensive and in-depth discussion of all current wireless power transfer (WPT) methods and meet the growing need for a detailed understanding of the advantages, disadvantages, and applications of each method. WPT is a game-changing technology, not only for IoT networks and sensors, but also for mobile chargers, long-flying drones, solar-powered satellites, and more, and the list of potential applications will continue to grow. Each author’s chapter is based on a minimum of 13 years and a maximum of over 30 years of research experience on selected WPT technologies to explain the theory and advantages and disadvantages of this to various applications. The book provides an insight into WPT theories and technologies, including inductive coupling for short-distance WPT, radio waves for long-distance WPT, optical WPT using lasers, supersonic WPT in water, and more. The characteristics of each WPT method are compared theoretically and technically. The differences of each WPT method are explained with reference to the different theories, techniques, and suitable applications. The reader will gain an understanding of the recent and future commercial market and regulations regarding WPT. They will be able to apply this knowledge to select the appropriate WPT method for their desired application. This book is appropriate for students, WPT researchers, and engineers in industry who are developing WPT applications.
